oovnn FOR CANS Ann mum's Application filed July 2, 1926. SeriaI No.120,028. 3

This invention has relation to covers for cans, receptacles, or thelike, made of metal, and more particularly cans such as are employed ascontainers for handling and shipping frozen eggs.

A wooden cover is usually employed for closing such cans, the interiorsurfaces of which are lined with sheet metal. The practice has been tofix the lining by nailing it to the sides of the cover, and to fastenthe cover to the can by nailing strips of flexible metal at regularintervals to the marginal portion of the cover, andthen to tuck orengage the free end portion of the strip in between a downwardly turnedbead and the upper edge portion of the can. Such practice isdisadvantageous, from the fact that the strips are nailed to the cover,as, in handling and transportation, the nails are liable to work'looseand allow the cover to become loose or unfastened, and from the factthat individual fastening elements are used for retaining the lining inplace on the cover.

In accordance with the present invention, therefore, the strips orelements which are utilized for inter-engagement with the can are formedintegral with the lining of the cover, so that the nailing operation isdispensed with and a more permanent securement of the cover to the canis afforded and the lining is retained in place on the cover without theneed of individual fastening ele ments, by spinning it over onto thetop'face of the cover.

On the accompanying drawings, Figure 1 is a section through a side of acan, showing the head at the rim thereof.

Figure 2 represents a plan view of a cover embodying the presentinvention, fastened to the can.

Figure 3 illustrates a section on the line 38 of Figure 2.

Figure .L is an enlarged plan view of a portion of the cover, showing acover fastening element. I

Figures 5 and 6, respectively, show detailed sections on the lines5-5'and 6-6 of Figure 4.

connection with which the cover of the pres i i ent inventionis used. Inactual practice, the cans may, for example, beabout 12 inches in: heightand about 10 inchesin diameter, orof any other commereial size. Theconst ruc-i tion of the can, however, forms no part of the presentinvention,except insofar as it isin combination with the cover; r Y 'Atthe upper edge of the'ca'n,the metal is bent downwardlyand thence.upwardly in the formwof a head 2, of doublezthick'ness, which abuts,against the rim. 1 The head constitutes the element of the canforinter-em gagement with the fasteningelements of the cover. Any othersuitable beadconstruction may be i used, if desired.

:The cover 8, as shown, is made of ,wood, I

and is of the proper size to fit Within the can opening. The cover isinteriorly lined with sheet metal, which overlies 'itsinteriorsurfaceand side and 1s securedto the cover by a flange 4 which is'spun overonto the top 01' moreover, fastening elements '5, are formed integralwith the liningof the cover, preferably at regularly spaced intervals,as at each quadrant. at the margin thereof. Each fas-, toning element isin the form of a strip, the free end of which is folded back on itselfto form an engaging element 6 of double thickness, thereby strengtheningthe element and giving an edge 6 against which a suitable tool may becaused to act.

The cover is secured to the can by tucking the element 6 in between thebead2 and the seam of the can, as shown in Figure 5, there by prying theseam away from the upper edge portion of the can at'the desiredintervals, and eflt'ectinginter-engagement of can and cover.

By the practice of the present invention, the use of individual.fasteningelements is eni I i In accordance With thepresent invention,

tirely done away with, both in securing the lining to the cover and infastening the cover to the can, producing thereby a more economical andeffective package.

Having thus described an embodiment. of this invention, itshould beobvious that it is susceptible of various changes and modificationswithout departing from its spirit orv scope as defined by the appendedclaims.

I claimzjl V. i

1. The combinationwith a can, of a wooden cover for closing said canhaving a metal lining covering the interior surface thereof and securedthereto by a flanged marginal portion of said lining spun over theexterior surface thereof and projecting exteriorly from the marginalportion of the cover and resting on the upper edge of said can.

2. The combination with a can having an exterior bead at the upper edgeportion thereof, of a wooden. cover forclosing said can,

havinga metal lining covering the interior I surface thereof anda-series of spaced fastening elements integral With said; lining andinter-engaging with the bead of said can.

3. Thecombination with a can having an exterior bead at the upper edgeportion thereof, of a wooden'cover for closing said can having a metallining covering the interior ao surface thereof and secured thereto by aflanged marginal portion of said lining spun over the exterior surfacethereof, and a series of spaced marginal fastening strips integral withsaid'lining and inter-engaging with the 'bead of said can;

4. The combination witha can having an exterior bead of double thicknessat the upperfedge portion thereof of a wooden cover for closing said canhaving ametal lining m -covering the interior surface therof and securedthereto by a flanged marginal portion of said lining spun over theexterior surface thereof, and a series of fasteningstrips spaced aboutthe margin of-saidcover and integral 1-3with said lining inter-engagingwith the bead of said can the inter-engaging portion of said strip beingof double thickness and presenting an edge against which a tool may bebrought.

In testimony whereof I have affixed my signature. I
